DETACHABEE DEvIcE FOR OPERATING- AwNI NG-wINcHEsQ To all whom it may concern.

Be it known that I, Aueusr B. RIPPE,a

citizen of the United States, and a residentof Salt Lake City, the county of Salt Lake,

I and the State of Utah, have invented a cer-' tain new and useful Detachable Device for Operating Awning-Winches, of which the following, together with the accompanying l drawings, forms a full, clear, and exact specification, which will enable others-skilled in the art to which it appertains to make and use the same.

My invention relates to a" detachable de- 1 vice for operatingthe winches in common use for raising-and lowering awnings, and

especially to those winches of the'so-called self-locking'worm gear type. The principal objects. of this invention are: first, to provide a downwardly extending rod for operating awning winches,

' means being provided whereby the rod may be quickly attached or detached, thus. making it 'possible'to use one rod for a considerable number of awnings and effecting a great saving in the first cost of the awning,

second, to provide a device which shall be efficient, simple and durable, besides economical in cost; third, to eliminate the unsightly permanent shafts and the so-called crank boxes such as are in general use at .the present time, thus improving the appearance of a building and avoiding damage suits due to passers-bycolliding with the crank 'boXes; fourth,to make it difficult for unauthorized persons to tamper with the awnings; and fifth, to make it possible to apply the present device to existing winches without making any changes in the'winches themselves. I

In order to clearly show the application of this device, the construction of ordinary awnlngs' Wlll be described first.

Awnlngs in common use at the present time are so made as to have a rod of wood or "other suitable material fastened to the canvas at the lower edge of the awning, the

said rod being supported on arms whichare hinged to the building. The upper edge. of the awning is fastened to a roller which is ournaled in brackets fastened to the build- Specificationof Letters Pateiit. Application filed December 28,1918. Serial no. 268,611.

- a casing and-forming What is wellknown as a" .winch of the self-locking worm gear type.

. The worm of the winch usually has shaft portion which projects outside the casing andat its GIICl'CtLI'I'lGS a universal joint, connecting the worm shaft to an operating shaftstanding at any required angle with relation to the worm shaft. The operating shaft usually extends downwardly to apoint easily reached by a person desiring to raise or lower the awning, and the lower end of j theoperating shaft is journaled in What is usually termed a crank box the latter being permanently attached to the building and'provided with means whereby the operating shaft may be rotated, thus imparting motion to the universal joint, and through the winch, to the awning roller. The operating shaft and the crank box mar the appearance of a building and'in the case of a building where the crank box must be attached to brick or stone, the: crank box is decidedly objectionable owing to the impossibility of makinga durable fastening.

The mechanism so far described, forms no part of the present invention. Briefiy,i the invention comprises a stem having suitably disposed hooks and a separate rod having,

hooks. adapted to interlock with the. hooks on the stem, s0 rotative motion may be communicated from the rod to the stem. The

stem is adapted for. fastening to the universal joint of any ordinary awning winch in the place of the usual operating shaft, while the operating rod may be attached to, or detached from, the stem, as the user may desire. V

The features of this invention, on which protection is desired, are collectively grouped in the appended claims.

In the drawing,

Figure 1, represents a perspective view'of the stern and its hooks;

In using this device, the hooks on the rod 17 are hung over the hooks on the stem 10 as shown in Figs l and 4, the position of the hooks belonging to the rod 17 being indicated by the dotted lines in Fig. 1. The rod 17' may be readily rotated by means of the handle 19 and the crank 18 in the hands of the user.

2. In a detachable device for operating awning winches, a stem adapted to be fastened to the driving member of a winch, hooks projecting outwardly and upwardly separate from the said stem, hook standing portions originating at an end of the said portions and point portions being adapted to co-act with the stem hooks, and means for rotating the said rod.

5. In the device described, a stem adapted for-fastening to the motion-receiving-por? tion of an awning winch, hooks projecting from the said stem, a rod separate from the said stem, hooks projecting from an end-of the said rod, the said'hooks having standing portions extending outwardly from the said rod with backwardly extending point portions, the said rod hooks being adapted to co-act with the said stem hooks for the purpose specified. i
